NHIED STATES JOHN P. KING, OF PROVIDENCE, RHODE ISLAND, ASSIG'NOR, BY DIRECT AND MESNE ASSIGNMENTS, TO IDEAL BRAIDING MACHINE COMPANY, A CORPORATION OF RHODE ISLAN D.

CARRIER FOR BRAIDING MACHINES.

Application filed January 6, 1922, Serial No. 527,381. Renewed December 1, 1922.

To all 'whom t may concern.:

Be it known that I, JOHN P. KING, a citizen of the United States, residing at Providence, in the county of Provldence and State of Rhode Island, have invented certain new and useful Improvements in Carriers for Braiding Machines, of which the following is a specification. l

This invention relates to improvements 1n the construction of carriers for braiding machines, and has for its object to provide such a carrier which is particularly adapted for running at a high velocity, being of a very strong and durable constructlon and yet light in Weight, the operating parts of the carrier being mounted to properly control the let off of the yarn or thread while running at a high rate of speed. This case 1s a continuation in part of my former abandoned case, Serial No. 347 ,278, filed Dec. 26, 1919.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawlngs,

Figure l is a side e evation partly 1n section showing the construction of my 1mproved carrier.

'Figure 2 is a perspective view of the weight-carrying standard member looking from the rear and showing a slot in its front, side and rear Walls by means of which slots the latch may be guided when in operative position, and also removed from the lstandard when desired.

Figure 3 is a perspective view of the latch member showing the feed-controllingyiinger mounted on its spindle.

Figure 4 is a perspective view looking at the inner side of thebottom weight.

Figure 5 is a perspective view of the base member of the carrier.

Figure 6 is a perspective view of the carrier standard supporting member. 4

Figure 7 is a view of the rear of the carrier showing the supportin projection on the bottom weight as entermg the complemental slot in the base member to support the weight against the shock of engaging and throwing the stop mechanism.

With reference to the drawings, 10 designates the base portion of the carrier, which is provided wit a longitudinal rib 11, bored at l2 for the reception of a'spindle 13 on which is rotatably mounted a yarn package carrying spool 14.

Instead of forming the wei ht-standard integral with the base member preferably provide a standard 15 formed comparatively thin sheet metal into a combined tubular and trough shape, the back of the lower portion being open or in trough shape while the upper portion of the standard is in tubular shape.

The front wall of this upper tubular portion is slotted vertically as at 16 to permit the feed-controlling finger of the latch member 1T to slide vertically therein and this standard is slotted through its side wall as at 18 to permit `this latch finger when liIted out of its guide slot to be swung on the axis of its spindle 9 to permit the removal of the package, and the rear wall of this standard is provided with a narrow slot 19 to permit the passage of the reduced portion 20 of the finger to pass therethrough when it is desired to swing this portion to the rear to drop it through this slot for the purpose of removing the latch for inspection or repa1rs. v

In this upper tubular end of the standard I have preferably mounted a phosphor bronze or anti-friction bushing 20 which is bored Aat 21 to receive the upper end of the by folding spindle 9 and also to receive a spring 22 for exerting a downward tension on the latch, the upper end of this spring being secured to the reduced neck portion of the screw 23 whereby the spring may be readily removed by simply backing `out the screw. The body of this bushing member 20 is arranged to extend down into the tubular portion of the standard below its front slot to also provide a lower bearing 24 for the latch spindle 9, and the upper portionl of this bushing above the standard is provided with a laterally-extending head 25 in which a suitable thread guide 26 is mounted.

In order to rigidly attach this standard In order to further support the lower end of this standard I have provided an upward'- ly extending boss 31 on the base which projects into the lower end of the standard to firmly support it which is of advantage particularly when the bottom weight engages thestop motion.

'lhe lower portion of this standard member is provided with laterally-extending .guide flanges 32 on which is slidably mounted the bottom yarn tensioning weight 33. This weight is also preferably formed of sheet stock having laterally-extending wings 34 folded to provide inwardly-turned lips 35 to slidably engage the iianges 32 and to also engage and operate the usual stop motion when the yarn breaks, and the upper end of this weight is provided with an inwardly-turned tongue 36 to engage the latch spindle 9 and cause the latch to function when the weight is lifted sufficiently. The lower end of this Weight is provided with a downwardly-extending finger 37 adapted to extend into the notch 38 formed in the rear of the body portion for the purpose of firmly supporting the weight member upon receiving a shock of contact with the stop motion when this weight drops into stop position, and by this construction it will be seen that the shock of engagement with the stop motion is taken by the body member instead of by the standard member as would otherwise be the case.

In order to effect a quick return action of this bottom weight after having been lifted by the thread tension during the rapid running of the carrier, l have provided a spring 39, the upper end of which is connected to the hollow stud 4() in this weight which also serves as a guide eye for the thread, while the lower end of this spring is connected to the stud 41 fixed to the standard. l

ln this standard li have provided the usual guide eye 42 which cooperates with that in the weight to lift the latter into engagement with the latch causing it to function by the tensioning of the thread, but it is found in practice where the carrier runsv very rapidly and where the thread is led directly from the package through this guide |42 to the guide eye in the weight, that the sharp upward angle of the yarn when leading from the bottom of the package, has a tendency to lift the package and so prevent its proper functioning. Therefore in order to obviate this serious difficulty l have provided a laterally-extending arm 43 on the carrier standard supporting member in which is located a guide eye 44. 'llhis auxiliary guide eye is located in the standard and offset laterally therefrom towards the delivery side of the supply package thereby eifectually reducing the angle of pull and likewise the lifting ed'ect on the package as the yarn is rapidly drawn therefrom.

aia/leaves ings forl the latch spindle that the same is well guided against cramping while irr action; then again by providing a phosphor bronze bushing or bearings for this rapidly acting latch thatit is further prevented from wearing even with the minimum amount of lubrication; and third, by providing a spring to insure rapid action of the latch and also another spring to insure rapid action of the bottom weight the yarn let ofi' is properly controlled even when the carrier is running at a very high rate of speed.

Further, it will also be noted that by slotting the standard through its side wall that the latch finger when lifted from its front guide slot may rest upon the edge of this side Wall during the removal and replenishingFof the exhausted package.

he foregoing description is directed solely towards the construction illustrated, but l desire it to be understood that l reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.
